  Lost the prior log message ... [this is an empty commit]

  Prior revision fixes the last ap_server_root_relative() NULL return
  code potential segfaults.  It also quits trying to server_root_relative
  a logging pipe, since log pipes generally take arguments.  However, it
  ignores the PassPhraseDialog exec: since the argument to that shell
  mechanism is the server name itself.
